ALL™ detection technology is based on high-frequency acoustic emissions emanating from sites of gas or fluid leakage through orifices, cracks, and corrosion in pressurized systems.

Sensitive piezoelectric sensors mounted to the structure on waveguides transform these acoustic waves to electronic voltage signals, which are amplified, filtered, and processed to determine energy content.

The signal output is monitored continuously on each channel, and alarm levels can be defined independently by channel so that you will know exactly when and where a leak has occurred.

To detect the sound of leaks in a boiler, AMI has designed acoustic sensors mounted on the ends of waveguides.

To detect leaks in piping, valves, or feedwater tubes, AMI has designed sensors that are mounted onto these structures.
